My approach to the 'Build Your Own Redis' challenge.

Features

• Basic Commands:
  • GET
  • SET (with TTL)
  • PING
  • ECHO
• Concurrency: Supports multiple concurrent clients
• Persistence: Loads RDB files and serves the content
• Replication:
  • Performs replication handshake
  • Propagates commands to replicas
  • Supports the WAIT command
• Streams:
  • Create streams
  • Support XREAD and XRANGE commands
  • Support blocking reads (XREAD block)
  • Support different type of queries (with +, -, $, partially/fully create IDs)
• Transactions:
  • INCR command
  • MULTI and EXEC commands
  • Multiple concurrent transactions with failures within transactions

RUN

• Build:
  • go build -o redis app/*.go
• Basic execution:
  • ./redis --port 5678
• Parse RDB:
  • ./redis --dir ./redis-data/ --dbfilename dump.rdb --port 5678
• Run as replica:
  • ./redis --port 1234 --replicaof "localhost 6379"

After the server is running, you can connect to it via any Redis client, Including redis-cli; Ex: redis-cli xread block 10000 streams orange 0-110.

NOTE: The current version fully supports RESP V2.
